- Offsets -
An additional unintended impression, in whole or in part, of the stamp design on the face or back of a stamp, caused by wet printing ink coming into contact with the surface that bears the additional impression. Appears most commonly at the back of a stamp. The design appears reversed that is, it reads from right to left, instead of from left to right.
